Kentico 7 Export Selected Site specific Pages

Hi I have got my hands on Kentico 7 recently. I figured out and picked up basics quickly.
I have found that your inbuilt Export/Import site/objects module is quite friendly useful.
I have a question regarding that module.

I have created new pages in my site on my dev environment. How do I move those pages to QA and Staging.
I am able to export global objects like Page Templates and Document Types but not site specific pages.
